specification, and in which- PATENT SAMUEL M. RITTENHOUSE, OF PIONEER, OHIO.

Specification forming part" of Letters Patent No. 222,30'S3dated December 2', 1879; applicationfi led April 16', 18791 To all whom it may concern:

Be it known that I, SAMUEL M. RITTEN- HOUSE, of Pioneer, in the county of Williams and State of Ohio, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this Figure 1 is a side elevation. view, and Fig. 3 is a rear elevation.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to an improvement upon the windmill for which Letters Patent of the United States, No. 193,728, were granted to me on the 31st day of July, 1877 and it consists in so constructinga windmill of the class and constructed upon the general principles described in the said Letters Patent, that it shall be adapted not only to the pumping of water, but to all other mechanical functions for which this class of motors are-adapted-such as operating saw-mills, grinding-mills, &c.

In the drawings, A is the wheel-supporting frame, which is swiveled upon a tubular shaft or sleeve, B, bracketed upon one side of a standard or derrick, G.

D is the wind-wheel, which may be of any preferred construction, and d is its shaft, which is journaled horizontally in boxes on a in frame A, and has secured upon it the bevel-wheel E, whichgears with a pinion, e, keyed upon the upper end of a tubular shaft, F, inserted vertically through the frame-supportin g sleeve B.

G is the main vane, which is hinged frame A in the usual manner, and H is the auxiliary vane, the beam 71. of which is hinged upon frame A at right angles to G, and is provided with an arm or fork, h, which is hinged upon frame A in a line with the hinge or pivot of beam h, so that the auxiliary vane H will have a vertical'up-and-down motion in the arc of a circle, but is prevented from mov in g laterally; hence it will be seen that vane H, whatever its elevation, will always operate Fig. 2 is a top in a plane parallel to that of the wheel D. To

prevent the vane H from descending too low, its beam h is provided with a bracket or rod, 2', which, when the vane is in its lowermost position, will impinge upon the side piece of frame A nearest to it.

The auxiliary vane H consists of slatsjk k k, set parallel to each other, facing downwardly at an angle ofabout forty-five degrees, in crosspieces I 1 upon the beam It. By this construction and by the gravity of the vane the wind facing wheel D will not affect or operate the vane H unless it is. of unusual power or blow ing a gale.

Affixed upon beam h is a cord or chain, I. which passes over a sheave, m, upon the upper end of frame A, and down through the tubular shaft F of pinion 6. At the lower -end of the derrick or frame which supports-the mill and its operating parts this cord or chain is secured in a tubular swivel-block, a, working in a bracket, K, which is secured upon the inner aboard, which is placed in the trough to con tain the water, so as to automatically operate the auxiliary vane H, substantially in the manner and for the purpose described in my Let= ters Patent of July 31, 1877 but if, through suitable intervening mechanism, the lower end of the vertical rotary shaft F is geared with a circular saw or grinding mill, the free end of lever L is connected with a governor, so as to operate in like manner, as with the board and water-trough, for the purpose of checking the speed of the wind-wheel by turning it edge wise more or less to the wind. A

Having thus described my improvement, I claim and desire to secure by Letters Patent of the United States 1. In a windmill, the combination'of the 'm, horizontally-projecting auxiliary vane H,

hinged upon frame A in a plane parallel to that of the wind-wheel D, and providedwith the curved arm h, cord or chain 1, tubular shaft F, having pinion e and swivel-block n, for preventing the operating cord or chain I scribed, and a regulating-lever attachment connected with the auxiliary vane by a cord or chain passing through the tubular shaft, all arranged and operating substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afixed my signature in presence of two witnesses.
